On 3 May the Competition and Markets Authority (CMA) said it would refer the merger for a phase 2 investigation unless Cardtronics offered acceptable proposals to address these concerns by 10 May.
As Cardtronics has not offered these undertakings, the CMA will now refer the merger.
A decision on the merger will be made by a group of independent panel members supported by a case team of CMA staff. The deadline for the final report is 27 October 2017.
All information relating to the investigation is available on the case page.
